A member asked:

What is considered a high amount of neutralizing antibodies from a mrna covid-19 vaccine?

A doctor has provided 1 answer

Absolute number does not seem to count for much and different commercial assays give different values. Moreover, antibody is only part of the story. T cells (cellular immunity) plays a very large role but is more difficult to measure. For practical purposes, if you have a (+) antibody titer you are pretty much protected
